So, let me get this straight: you have a hard core Kyokushin school available to you for training, and you think that there's something that you'll get from American/Parker's Ken/mpo that wasn't in Kyokushin? What might be missing from Kyokushin is ground work--train Judo or Brazilian Jiu Jitsu rather than Kenpo, for God's sake. The stand-up training you got in Kyokushin is 10x better than anything you'll ever get in Kenpo.

If you can't spar with it, you will get fucked up by someone who does. A boxer will KO you. A wrestler will slam you. A BJJ guy will submit you. A decent street fighter will kick your ass. The only people you'll be able to fight will be those with no fighting skill at all. Not just those with LITTLE skill, because they'll still beat you.
